Isostatic phase transition and instability in stiff granular materials

, 1998
In this letter, structural rigidity concepts are used to understand the origin of instabilities in granular aggregates. It is shown that: a) The contact network of a noncohesive granular aggregate becomes exactly isostatic in the limit of large stiffness-

Study on the Ablation of Slide Plate by Pantograph–Catenary Arc Based on Pantograph Slide Material

Infrastructures
The ablation of pantograph sliders caused by pantograph–catenary arcing is a critical issue in the operation of pantograph–catenary systems. The arc discharge induces localized high temperatures that lead to the melting and even evaporation of the slider

Computational fluid dynamics-multibody system dynamics bidirectional coupling calculation and flow-induced vibration evaluation of a high-speed pantograph-catenary system

Engineering Applications of Computational Fluid Mechanics
Increasing the speed of a pantograph deteriorates its aerodynamic performance and aggravates the problem of flow-induced vibration, which is not conducive to the stability of the pantograph – catenary system (PCS). Currently, commercial high-speed trains
